高密度电阻率法在滑坡识别中的应用

高密度电阻率法在探测不良地质现象的过程中，能获取关于地电断面结构特征的大量信息等特点，因而它是地质灾害勘查中有效的地球物理勘查技术。在滑坡治理中，通过高密度电阻率成像探测法查明了滑坡性质和参数，根据探测结果，分析了该滑坡发育历程和破坏特征，对该滑坡的工程稳定性及其对环境的影响进行了评价，并提出相应的治理对策。

Application of High Density Resistivity Method in Landslide Identification

High Density Resistivity Method(HDRM) is an effective tool for landslide survey,and the suitable in-situ working scheme and its data analyzing model are the base to obtain believable results.An innovative data interpretation procedure for locating slide-face position in complex geological conditions is proposed.The apparent resistivity patterns of different types of landslide are different even if the landslide is investigated with the same electrical array.The ration parameter method can improve the capability of two dimensional apparent resistivity section to reflect the distribution of the object inside landslide.Some landslide disasters along expressway are briefly introduced.The geometry parameters and the interspace characters of the landslide are obtained.Researches are made on the occurrence mechanism and deformation characteristics of landslide according to disaster characteristics.The landslide stability and its effect on the expressway under application are appraised,and the reliability of reinforcement work is evaluated.The principles for preventing and mitigating the landslide disaster of this type are put forward.
